    Significance and Use

    5.1 This test method may be used for acceptance testing of commercial shipments of garments with attached buttons.

    5.2 This test method may be used to determine the compatibility of tack attached buttons or prong fastener attached buttons to fabrics used in apparel. In which case, the buttons are attached to the fabric in the manner in which they will be used and the combined units tested.

    1. Scope

    1.1 This test method covers the determination of the holding strength of a tack and prong fastener attached button using a tensile testing machine.

    1.2 This test method is applicable to attached buttons in garments or to be attached to fabrics intended for use in apparel (see Annex A1).

    1.3 Units—The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.

    1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

    1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
